The Lowdown
G’day, Rusty here, lookin’ at the next couple of weeks for Lakey Pipe. This is a run of solid, consistent swell from the southwest, so if you’re an experienced surfer, you’re gonna be smiling. The water’s sitting at 80°, which is pretty much spot on for this time of year, so no surprises there.
The action kicks off Sunday the 16th of August. We’ve got a clean 7ft SSW groundswell rolling in with a very long 16-second period. The wind’s a light cross-offshore breeze, making for clean faces all day. The combined energy is moderate (1982), so there’s plenty of push behind those sets. Lakey Pipe is a consistent reef break, so expect a proper wave. This is a solid start, but the real standout is coming.
Monday the 17th holds clean 5ft to 5ft SSW swell, still with a nice 14-second period. The wind stays light and cross-off. It’s excellent, but the size is a touch smaller.
Then Tuesday the 18th sees a jump back up to 6ft SW swell, with a 16-second period, and the energy is strong (2360). The wind is still clean.
Now, Wednesday the 19th of August is the big one. This is the highlight of the run. We’re talking 8ft to 8ft SW groundswell with a very long 19-second period. The combined energy is powerful (3913), and the wind is a light cross-offshore breeze. This is a proper, heavy reef wave for experienced surfers only. The long period means it’ll be thick and hollow, with long lulls between sets. The crowd factor is “often”, so get in early.
Thursday the 20th gets tricky. The morning swell is pushing 10ft, which is too big even for this break, and the forecast says so. The afternoon drops back to 8ft, but things get a bit questionable. The energy is still extreme (4303), so it’s a powerful ocean, but the conditions are marginal.
Friday the 21st the wind picks up to a moderate breeze, and the swell is still solid at 7ft to 8ft, but the forecast is marginal. The energy is still strong (3595), but it’s not the cleanest.
Saturday the 22nd comes back into form. Clean 8ft SSW swell with a 16-second period, light cross-off wind, and excellent conditions. The energy is strong (3152). This is another top day.
Sunday the 23rd holds clean 6ft to 6ft SW swell, still excellent, with strong energy (2064).
From Monday the 24th, the swell drops a little, but we’ve got clean 5ft to 6ft SSW swell for the first half of the day, then it gets marginal. The energy is moderate (1729).
Tuesday the 25th and Wednesday the 26th are marginal days with moderate breeze and smaller swell, energy dropping to 612. Nothing to get excited about.
Then Thursday the 27th of August, we see a bounce back. Clean 4ft to 5ft SW swell, but with a very long 19-second period. The energy is moderate (2459). This is a sneaky good day for the reef, the long period will make it steep.
Friday the 28th holds clean 7ft SW swell with strong energy (2527). The afternoon gets a little cross-shore, but it’s still rideable.
The last few days, Saturday the 29th through Monday the 31st, are a mix of clean and marginal conditions, with solid 5ft to 7ft SW swell. The energy stays strong (2640) on the 30th. It’s not a complete loss, but the earlier part of the window is where the magic is.
So, the standout is Wednesday the 19th of August. The other top pick is Saturday the 22nd. If you’re an experienced surfer, these are the days to lock in. The 27th is a sneaky long-period treat.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
